Incazelo kanye nezigaba zemboni yokubumba umjovo isho ukuthi ukubumba komjovo kuhlukaniswe ukubumba komjovo wenjoloba, ukubumba komjovo wepulasitiki nokubumba umjovo wokubumba: 1. Ukubumba umjovo wenjoloba: ukubumba umjovo wenjoloba kuyindlela yokukhiqiza ejova iraba ngokuqondile isuka emgqonyeni iwufake esibunjeni. ngenxa ye-vulcanization.Izinzuzo zokubunjwa komjovo wenjoloba yilezi: nakuba kusebenza ngezikhathi ezithile, umjikelezo wokubumba mfushane, ukusebenza kahle kokukhiqiza kuphezulu, inqubo yokulungiselela umbungu ikhanseliwe, umfutho wokusebenza kuncane, futhi izinga lomkhiqizo lihle kakhulu.
Incazelo kanye nezigaba zemboni yokubumba umjovo kukhombisa ukuthi 2. Ukubumba umjovo wepulasitiki: ukubumba umjovo wepulasitiki kuyindlela yemikhiqizo yepulasitiki.Ipulasitiki encibilikisiwe ijovwa esibunjeni somkhiqizo wepulasitiki ngokusebenzisa ingcindezi, futhi izingxenye zepulasitiki ezifunwayo zitholakala ngokubunjwa kokupholisa.Kunemishini yokubumba imijovo eyimishini esetshenziswa ngokukhethekile ukubumba umjovo.Njengamanje, i-polystyrene iyipulasitiki esetshenziswa kakhulu.
Incazelo kanye nezigaba zemboni yokubumba umjovo kukhombisa ukuthi 3. Ukubumba komjovo: umumo otholakalayo uvame ukuba umkhiqizo wokugcina, futhi akukho okunye ukucubungula okudingekayo ngaphambi kokufakwa noma ukusetshenziswa njengomkhiqizo wokugcina.Imininingwane eminingi, efana neqhubu, ubambo kanye nentambo, ingakhiwa ngesinyathelo esisodwa sokubumba umjovo.
Eminyakeni yamuva nje, ngokuthuthuka okuqhubekayo kwezobuchwepheshe kwe-China embonini yomshini wokubumba umjovo, ukuhwebelana kwe-China nokuthumela ngaphandle kwemishini yokubumba umjovo kube sesimweni esihle.Mayelana nokuthunyelwa kwamanye amazwe, ngokwencazelo kanye nezigaba zemboni yokubumba umjovo, isilinganiso sokuthekelisa semishini yokubumba yomjovo yaseChina sibonise ukuthambekela okukhuphukayo kusukela ngo-2015. Ngo-2021, umthamo kazwelonke wokuthekelisa wemishini yokubumba umjovo uzoba ngu-49294, wehle ngo-31.6. % unyaka nonyaka;Umthamo wokuthekelisa wawungu-US $1.693 billion, ukhuphuke ngo-39.6% unyaka nonyaka.
Ngokombono wentengo yokuthekelisa yemikhiqizo yomshini wokubumba umjovo, kusukela ngo-2015, intengo yokuthekelisa yemikhiqizo yomshini wokubumba umjovo waseChina ikhombise ukwehla kokushaqeka.Ngo-2018, isilinganiso sentengo yokuthekelisa yomkhiqizo womshini wokubumba umjovo kazwelonke sasingamadola ayi-16000/isethi, ephansi kakhulu eminyakeni yamuva, bese intengo yaphinde yakhuphuka.Ngo-2021, inani lentengo lokuthekelisa elimaphakathi lemikhiqizo yomshini wokubumba umjovo kazwelonke lalingamadola angu-34400/isethi, okuwukunyuka okuphawulekayo esikhathini esifanayo ngonyaka odlule.
Ukubumba umjovo kusetshenziswa kakhulu emkhakheni wezimboni, okuyindlela yokumodela yokukhiqiza umkhiqizo wezimboni.Ngokuthuthuka kwemakethe yokubumba umjovo, ubuchwepheshe bemboni yomshini wokubumba umjovo waseChina buhlala buthuthuka.
